I've been an Oracle DBA for quite a number of years, working on HP-UX systems. Now I'm also running some Oracle Application Server on Linux machines and I could use some advice about Oracle and Linux. For SL, I'm assuming I can call my SL 5.3 installation equivalent to Red Hat 5.3 for Oracle support purposes? In the Linux world things seem to move so fast. We have gone years between OS upgrades with HP-UX, and even then there's not a lot of difference as far as Oracle is concerned. I'm checking the Metalink site for a support matrix for various pieces of Oracle Application Server and SL(Redhat) 5.3. Things are all working in this configuration, but I'm nervous that maybe I'm outside the supported setup. Is it safe to do regular yum updates on a dedicated Oracle App Server/SL 5.3 box? Maybe I should just let it run at the current configuration and not chance breaking something. As you can tell, I'm a bit apprehensive about the speed of changes in the Linux world. If anyone knows a good resource for Oracle on Linux, I would be willing to hook up with a consultant for a few moments of good advice.
